Nokia 3310 Cell Phone LCD Digital Thermometer
If you have an old Nokia 3310 cell phone collecting dust in a drawer why not put it to use? This Nokia 3310 Cell Phone LCD Digital Thermometer project uses a one wire DS18B20 and a Microchip PIC 12F629 microcontroller to take control of the old LCD directly. There is code, schematic and a foil pattern available on the site. Via: Team Droid
